Apr 19, 2024Owncast is an open source, self-hosted, decentralized, single user live video streaming and chat server.CVE-2024-31450 · Other software · owncast · reported by GitHubLow 2.7
Owncast is an open source, self-hosted, decentralized, single user live video streaming and chat server. The Owncast application exposes an administrator API at the URL /api/admin. The emoji/delete endpoint of said API allows administrators to delete custom emojis, which are saved on disk. The parameter name is taken from the JSON request and directly appended to the filepath that points to the emoji to delete. By using path traversal sequences (../), attackers with administrative privileges can exploit this endpoint to delete arbitrary files on the system, outside of the emoji directory. This vulnerability is fixed in 0.1.3.

Where this comes from: the exploited list is CISA’s Known Exploited Vulnerabilities catalog. Everything else is the whole National Vulnerability Database, where each record is published by the team that found the bug (Wordfence, Patchstack, WPScan, the vendors themselves and others); we show who. Exploit odds are FIRST’s EPSS, updated daily. Titles and categories are ours, so check the linked record before acting on a detail. For a write-up of the big ones, see our advisories. Every vendor, and every WordPress plugin and theme with a recorded flaw, also has its own page. All of it is free to reuse as JSON, CSV or RSS.
